WATER-GAS GEN ERATO R.

SPECIFICATION forming part of Letters Patent No. 484,730, dated October 18, 1892. Application filed June 6, 1891. Serial No. 395361- (No model.)

To all whmn it may concern:

Be it known that I, REINHOLD BoEKLEN,a citizen of theUnited States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented a new and useful Improvement in Water-Gas Generators, of which the following is a specification.

This invention relates to improvements in water-gas generators in which the gases generated in the fuel-chamber are passed through a carbureting-chamber and then through a superheating-chamber, from which they are discharged in the atmosphere while blowing up the fire and while gas-generating are discharged into the hydraulic main, seal, or washbox.

One object of this invention is to aid the blast with gas, so as to heat and light up more rapidly the carbureting and fixing chamber of the water-gas apparatus to diminish the blast time and fierce blast under the fuel in the fuel-chamber, so as to save fuel, avoid clinkering, and damaging the furnace or f uelchamber. A second object is to provide a horizontal cross-partition atv the parts where the water-gas and the products of hot oil enter the carbureting-chaniber to check the passage of the water-gas horizontally, allowing time for the products of the oil to pierce through it vertically, and a third object is to provide an open overflow to the base of the carbureting-chamber in order to exhibit to the operator when surplus oil is charged into the chamber beyond the capacity of heat for decomposition, and thereby enabling the operator instantly to regulate the oil-feed during gasmaking, and thus prevent loss of oil and avoid undue forming of hard carbon over the brickwork, thus preventing the disabling and choking up of said chamber and obviating the necessity of rebuilding of the checker brickwork.

In the annexed drawings, illustrating the invention, Figure 1 represents a side elevation of the generator with my improvements. Fig. 2 is a central vertical longitudinal section of the'same. Fig. 3 is a horizontal section of the upper portion of the chambers of the same, taken on the line 2.2 of Fig. 2. Fig. 4 is a vertical lateral section of the fuel-chamber of the same, taken on the line 00 a: of Fig.

i 2. Fig. 5 is a similar section of the carbureting-chamber of the same, taken on the line y y of Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

A represents the exterior metal shell inclosing all chambers of the generator. It is provided with strong T-iron horizontal and vertical .bands and strips to stiffen its sides. The bottom of this shell is covered and the sides and ends are lined with walls of firebrick, and a strong longitudinal arch B of fire brick from side Wall to side wall protects the top of the shell. By means of the lateral vertical partition-walls O and D the generator is divided into three vertical chambers, the fuel-chamber E, the carbureting-chamber F, and the superheating-chamber G. At the top of the wall 0 is or are one or more openings H, through which the gases pass from the fuel-chamber to the carbureting-chamber, and at the bottom portion of the Wall D is a large opening I, through which the gases pass from the carbureting-chamberinto the superheating-chamber. The fuel-chamber is furnished with the grate J over the ash-pit K, and at its top is made the coal-inlet and sealdoor L, and at the front side is provided near the grate a door M, and below it to the ashpit is made the ash-seal door N, and in said ash-pit is furnished the steam-nozzle 0, connected with the steam-supply pipe and valve P. The carbureting-chamber F has furnished through its top the oil-supply nozzles Q.

At the top of the superheating-chamber G is provided the gas-outlet seal-door R upon the outlet T-casting, which has the standpipe S, connecting with it the wash-box U. The carbureting and superheating chambers have a common bottom made inclined, and an overflow-pipeVis connected and conducts any surplus oil and tar from said bottom into a tar-well W, provided in which the pipe V is sealed by the liquid contained in the well.

X represents the main blast-pipe, connected with a pressure-blower. From said main X are three branch blast-pipes X, Y, and Z, of which each is furnished with a quick-opening gate-valve a, b, and cto regulate the blast in'each branchpipe independently and furnish the required air for the proper combustion of the gases in the relative chamber. The blast-pipe X is connected and delivers the air into the ash-pit for the fuel in the fuelchamber. The blast-pipe Y conducts the air through the passage d into the carburetingchamber, and the blast-pipe Z forces the air into the superheating chamber, to which is also connected a gas-pipe Z having the valve Z, said gas-pipe connecting from the gas-space in the wash-box to the fixing or carbureting chamber, or to both. The gases from the fuel in blowing up pass through the openings H into the carbureting-chamber and are passed downward and meet from the passage d the air-blast from the pipe Y and passing through the opening I meet the blast from the pipe Z and pass up through the superheating-chamber and out through the seal-door R.

Now to save time and fuel in blowing up and heating the carbureting and fixing chamber I provide the gas-pipe connecting the gas-space of the wash-box with either the fuel, carbureting, or firing chamber, or with all of them, either to the chambers direct or through the blast-pipes, so that by furnishing gas with the air-blast a bright combustion is readily passed through the carbureting and firing chamber, and the heating of them is done more rapidly than by forcing with the blast into the fuel fiercely to cause the flame from the fuel to pass entirely through these chambers. By

. this means of aiding the blast with the gas from the wash-box the blast into the fuel can be greatly reduced, so as to avoid clinkering and wasting fuel and damaging the brickwork of the fuel-chamber.

The carbureting-chamber F is constructed with a horizontal cross-partition from wall to wall e of tile plate to form a distinct compartment in the top of said chamber, the bot-- tom of which compartment is nearly level or a little below the openings H into the fuelchamber E, and the oil-nozzles Q discharge vertically down upon the horizontal bottom or cross partition or tile e, which is perforated with a number of small holes, as shown, so that the water-gas entering from the fuelchamber E is checkedin its passage by the partition or perforated tile e and is pierced by the oil, and its products being forced down through the water-gas under said plate e are laid alternately in lateral and longitudinal rows of three-cornered tile bars f, which rest upon rows of checker-bricks g, forming tor tuous gas-passages. At the junction and base portion of the carbureting and superheating chambers is located a combustion-chamber, above which the superheating-chamber is most entirely occupied by brick checkerwork h. The top surface of the perforated tile plate e has upward projecting taperpoints for assisting the diffusion of the oil, for which purpose the bars fare also employed. At the period of generating the Z' and valve Z illuminating gases the steam from the nozzle 0 passes into the ash-pit and from it through the incandescent fuel, and the gaseous products pass into the carbureting-chamber, in which from the oil-nozzle Q the gases are enriched and mixed and pass into the super heating-chamber and through its checkerwork becoming fixed, and finally pass through the stand-pipe S into the wash-box U, from which they are conducted, as usual, to the condensing apparatus, and so on.

For the purpose of drawing off the gases held in the generator at the termination of a gas-charge and after the oil and steam supply are stopped I employ on the stand-pipe an exhaust-fan t', the inlet of which is connected with the pipe S, and the case of said fan has a downward outlet-pipe j, passing into the wash-box and into the water much lower than the pipe S, and'is provided at its lower end with a perforated outlet I. Said fan has a belt-pulley by which it is rotated from a suitable motor or engine. With the stand pipe or fan is connected a proove-light and a water-pressure gage to exhibit in the engineroom the quality and pressure of the gases passing in the stand-pipe. At the time of the end of a gas-charge, when the pressure in the generator is reduced by the stoppage of the oil and steam supply beyond that of the gasholder at the seal of the stand-pipe in the wash-box, said fan i is set in motion. fan thereupon draws off the gases from the generator and forces them into the wash-box. As soon as either the quality or pressure of the gases passing in the stand-pipe exhibits by the test-light or pressure-gage a low quality or undue low pressure said fan iis stopped and the gas-outlet seal-door R is'opened, and the air-blast is started to blow the generatorfire and heat the chambers of the generator for the next gas-charge.

The object of the gas-pipe, which contains the valve Z and extends from the wash-box to the fixing-chamber, is to enrich and supply gas to the blast and promote the heating of said chamber.

From the foregoing will be observed that by the overflow-pipe V a means is provided for the operator to observe in the well W oil flowing from the carbureting-chamber therein and thereby warning the operator of an undue feeding of oil, too rapid for the heat in the chamber to decompose, and therefore at once to regulate or stop said oil-feed. Thereby the usual rapid accumulation of hard carbon in said chamber is prevented and the chamber is preserved from being clogged and choked with hard carbon, and it remains in working order for a long time before requiring to be "laid off to cool and clean and renew its brick work,-as such chamber requires very often.

In the construction and the combined blast of this generator the area of each chamber is reduced from the fuel or first to the super heating or last chamber. Thereby the force IIOv of the blast is increased toward the last, the Walls 0 and D are heated on both sides, and are heated highly in short time and kept hot a long time. The products of combustion from the fuel travel Very short distances while hot and meeting powerful supply of air for combustion and causing quick ignition of the products and very rapid heating of the chamber with reduced consumption of fuel and time wasted during the blast period. During the gas generating period said gradual-reduced area of the chambers causes an increased friction upon the generatedgases, re-

tarding the passage more and more of the unfixed vapors, but rapidly delivering the permanently-fixed gases to the wash-box.

The generator with one shell, its bottom and sides lined with walls, and one arch B under the top, and the cross-walls O and D, is an extremely strong and durable construction of limited expense. The perforated plate 0 at the top of the chamber insures the proper diffusion of the oil, while it holds it to the action of the hot gases as they pass into the carbureting-chamber, insuring their perfect carburetion.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a water-gas apparatus, the combination, with the carbureting and fixing chamber and the wash box or seal, of the gas-return pipe from the gas-space beyond the seal in said wash-box to the carbureting and fixing chamber to aid the air-blast.

2. In a Water-gas generating and carbureting apparatus, the combination, with the carbureting-chamber having the oil-inlet nozzles located in the upper portion, as shown, the brick checker-work, and the gas-outlet, of a horizontal perforated cross-partition extending from wall to wall and located below the oil-nozzles and the water-gas inlet and above the checker brickwork, the overflow-pipe connected to the base of said chamber, and the open oil and tar well, substantially as and for the purposes herein shown and described.

In testimony whereof I hereunto set my hand this 2d day of June, 1891.
